Toyota fuel injector cleaner bottle difference?

[aamirq]

I have a question to ask most Toyota fuel injector cleaners that iv seen at shops have this specific line written that they are meant for d4 engines and it is a 200ml bottle.
today I saw a Toyota fuel injector cleaner bottle which only had "for all gasoline engines" written and the picture of the injector was different with a sticker on it of Indus motors which was proof that it's a genuine Toyota injector cleaner and this was a 182ml bottle. And part numbers varied on both of the bottles. Can anyone please explain the difference between the two bottles?? Has the packaging changed or what?

its the same thing as other STP additives.
there is no such things as NEVER USE THEM, there is no harm, they can either do good or do nothing.
but there is no point in using them, once injectors get to the clogging point - then they need proper injector cleaning job and laboratory
e.g. magic motor lahore are authorized service center for ASNU injector cleaning sytems
also do not be fooled by adding hi-octane constantly it has nothing to do with cleaning
hi octane should not be mixed beyond 20%-25%.
if you'are having no problems then use it one bottle every 2,000 kms that is all. and if you are having some problems with injectors this is not going to solve it, MOST probably

I am using Toyota Corolla 2004, Chassis No: NZE121-3046658. I want to use Toyota Injector Cleaner. What is your suggestion? Which cleaner i use? D4 series petroleum engine or all petroleum engine? What is the basic difference?

[Xulfiqar]

D4 means direct injection engine - the other is one for port injection engine.

This product is used with a pressurized canister and a fuel line block/diverter, That way this mixture is in "neat" form in the fuel rail and the injectors, it only cleans a little bit (almost no difference in a newer engine).

I can bet you toyota showrooms in Pakistan wont have that canister/valve

I have also used these Toyota Fuel Injector cleaner on every periodic maintenance of my car. Toyota suggest these to be used every 3 months or 5000 KM. My car goes for maintenance every 6 months and around 4500 KM. I have once asked these ppl on first maintenance what these addictive will benefit for car and they said JDM cars (like Vitz) has knocking problem which customer faces commonly due to low quality of fuel in order to avoid or reduce knocking and use these additive every 3 months or 5000 kms.

My question is how these liquid remove dirts and where dirts will go on driving a car is it go on CAT and in response CAT clogged easily with usage of Fuel Injector Liquid?

What other option do you have?

On turbo cars when we install the water/meth injection kits,we see that apart from adding power,the methanol cleans the intake ports/valves and also exhaust ports/valves.

Now thats some cleaning right there!!

Other option is to do Ultrasonic Fuel Injector Cleaning by Physically cleaning of fuel injectors and about low quality fuel problem then we use 30 - 70 mixture of High Octane and normal petrol. This is the only solution left i guess.

ultrasonic baths cannot be done on regular basis as it actually does erode part of the injector pintle assembly, This is the reason that most car manufacturers recommend a "dialing in" of the fuel tables after this.

If you dont do the dial - then your long term trim will always be somewhere in the below negative 5 or 7% range no matter what you do to the system.

This liquid is nothing more than any other OTC injector cleaner product - Toyota do not recommend this on a regular basis specially on dead head (returnless) fuel system cars as the fuel passing through to injectors goes through the filter once only - this keeps the filter pretty clean and thats why they can advertise it as replace every 100,000 kms or something.

btw - when you dunk this in fuel - it makes very little difference, might as well assume its in, to get real results from this you need the pressure canister.

Sorry guys, all rubbish commentary here. No need to use them, unless there is some clogging and in which case best products are not available in pak. YES they CAN do damage to your engine parts. Some toyota service centers reccommend them cause they have a product to sell. Honda does not reccommend using cleaners or power booster fuels. They do nothing. There are several factor at play here that determine whether n if injector or fuel lines get some sort of blockage. Using these as a regular maintenance is even more stupid
